CodeIgniter表单验证方法实例详解_PHP

1.在D:\CodeIgniter\system\application\views目录下写一个视图文件myform.php

<?php echo $this->validation->error_string;?>
<?php echo form_open('form/index');?>
Username

Password

Password Confirm

然后再写一个视图文件formsuccess.php

<?=anchor('form', 'Try it again!'); ?>

2.在D:\CodeIgniter\system\application\controllers目录下写一个控制器文件form.php

<?php
class Form extends Controller{
 function index(){
 $this->load->helper(array('form','url'));
 $this->load->library('validation');
   $rules['username'] = "required";
    $rules['password'] = "required";
    $rules['passconf'] = "required";
    $rules['email'] = "required";
    $this->validation->set_rules($rules);
 //    $this->validation->set_error_delimiters('','');
 $fields['username'] = 'Username';
 $fields['password'] = 'Password';
 $fields['passconf'] = 'Password Confirmation';
 $fields['email'] = 'Email Address';
 $this->validation->set_fields($fields);
   if ($this->validation->run()==false) {
   $this->load->view('MyView/myform');
   }else {
   $this->load->view('MyView/formsuccess.php');
   }
 }
